When is extra postage needed

The Postal Service charges extra postage when mail pieces are non-machinable. Pieces that are rigid, extra-thick or unusually shaped, can jam postal equipment and be difficult to process. This costs the Postal Service time and money—and may also damage your mail piece. First-Class Mail letters that have one or more non-machinable characteristics require special handling as these pieces cannot be processed using automated equipment and must be processed by hand.

This is referred to as "hand-cancelling", which stamps a mark on your postage stamp so it cannot be reused.

You will pay a non-machinable surcharge for this service.
